SPECIFICATION forming part of Letters Patent No. 349,221. dated September 14, 1886.

Application iiled July 8,1886. Serial No. 207,470. (Nomodel.)

To all whom it may concern:

Be it known that I, JoHIEL JacxsoN, a citizen of the United States of America, residing at Fort Atkinson, in the county of Jefferson and State of Visconsin, have invented certain new and useful Improvements in Springs for Vehicles; and I do hereby declare the following to be a full, clear, and exact description ot' the invention, such as will enable others skilled in the art to which itv appertains to make and use the same, reference being had to the accompanying drawings, and to letters or iigures of reference marked thereon, which form apart of this specification.

My invention relates to certain new and useful improvements in springs, the object of my improvement being to provide a novel spring for side-spring vehicles that will be comparatively cheap in construction and effective in operation, so as to provide an easy-riding vehicle; and to this end my invention consists in the construction and combination ofthe parts, as will be hereinafter fully set forth and specifically pointed out in the claims.

In the accompanying drawings, which illustrate my invention, Figure lv is a side view showing my improved side spring attached to a vehicle. Fig. 2 is a plan view of Fig. l. Fig. 3 is an end view, looking toward the front end of the vehicle. Fig. 4 is a detail perspective view of a rear portion 4ot' a vehicle, showing a part of my improvement applied thereto. Fig. 5 is a side view of my improved spring detached 'from a vehicle, said view showing my improved stiffener-bar applied to said spring. Fig. Gis a sectional view taken through the line :c :v of Fig. 5, and Fig. 7 is av detail perspective view of the stiffeuing device detached from the vehicle.

A refers to the rear axle, which is connected to the front axle, A, and bolster a bythe converging reach-bars B B, said bars being braced to the rear axle by braces b l). The front portion of the reach is provided with the usual head-block, B', with curved plates bj between which the fifth-wheel is located, these plates b b being attached to the front axle and bolster a, in any suitable manner.

c c refer to clips for attaching the rear ends of thereach-bars B B and the braces b b to the hind axle, said clips also serving to hold and maintain in position a flat bar, C, which is lare secured to each other by clips f f.

)provided with an upwardly and inwardly curved portion, O', the terminal portion ot' which is flattened, as shown at d. rIhe inner ends ofthe bars or plates O will be located on a line with the outer ends of the bolster a, to which the side springs, F, are attached. rIhe bars C, owing to their peculiar construction, will be light and perfectly rigid against vertical movement.

To t-he ends of the bolster a are attached clips e, which are provided with downwardly- Vprojecting ears for securing the same to the bolster, and upwardly-projecting ears, through which pass bolts for pivotally attaching thereto the semi-elliptical side springs, F. 'Ihe springs F have the lower plates thereof bent at their rear ends upon themselves, s o that they will embrace the flat terminal portion, d, of the bar or support O, to which said springs are attached by means of bolts d. The front ends of said springs F are formed into eyes,

through which pass securing-bolts. The lower portion of the spring F, hereinbefore referred to, consists of a suitable number of leaves or plates, the ends of said plates or leaves each being provided on both sides with downwardlyprojecting portions f, which will lie over the edges of the leaf adjacent thereto. The center of the spring F should be a slight distance nearer the rear 'axle than the forward axle. The upper plate, G, of the spring F has an upper long leaf, g, the ends of which extend upwardly and are supported by shorter leaves m, as shown. The ends of the long leaves g are secured to transverse straps II H in any suitable manner. The leaves of the side spring rIhe straps H II extend under t-he body ot' the vchicle, the end portion thereof being bent npwardly and outwardly, and the outwardlyprojecting portions h have the ends of the spring g secured to them by means of suitable bolts or clips. Above the raised front end portion of the side spring a strap with'footrest is secured by the same bolt which attaches the strap H to said spring.

Instead of flattening the end ofthe bar G, it may be given ahalif twist or turn, lso as to bring the end portion to ahorizontal position..

\Vhen it is desired to stiii'en the spring, I make use of the bar I, as shown in Fig. 7, said bar having a straight portion, i', which is of a ICO greater length or distance between the clips This bar is then bent outwardly at each end, as shown at j, and is provided with downward]y-projecting portions i, which will lie above the top platieot' the spring F. The bar I may be advantageously used when two persons are riding in the vehicle and one is ot' greater weight than the other, or it may be used between the leaves of the spring should the vehicle sagmore on one side than the other. This bar I is simple in construction, and may be readily applied to and detached i'rom my improved style ot' side spring.

rlhe spring hereinbefore described is simple in construction, and will permit the body to have a freevertical movement as well as a lateral movement, and sufficient backward or forward movement of the body is provided l'or by the bent portion C of the bar C to relieve the vehicle fromjars in the line ot' drai't.

I do not wish to confine myself particularly to the precise l'orm ot' spring or the (,onstrucA tion ol' the parts hereinbefore shown and described, but reserve the right to modit'y my invention within the scope ot' my claims.

I claimm l. In combination with a side spring for vehicles, having leaves which diverge from each other, a detachable stiffening-bar, I, adapted to be placed between the springs at or near their diver-ging points, substantially as shown, and i'or the purpose set t'orth.

2. As a new article ot' inanulaeture, a stift'- ening-bar, I, having the end portions bent outwardly and downwardly, substantially as shown.

V2l. In combination with the side spring, F, consisting of a series of leaves which are se cured to each other, spring G, secured above the same, and a sti ft'ener-bar, I, adapted to be inserted between said springs and maintained in position by downwardly-projecting 'portions i, which embrace theedgesol' the lower spring, substantially as shown.

4. In a side-spring Vehicle, a spring having diverging sections, as shown, which are attached centrally to eaeh other, the ends ofthe lower section being attached to bent bars seeured-to the rear axle, and the l'ront ends to the bolster a, the ends o1' the upper sections being attached to straps II II, substantially as shown, and l'or the purpose set i'orth.

5. In a vehicle, the combination ofthe lon gitudinal springs attached at their iorward ends to the bolster and at their rear ends to bent bars which project above the plane ot' the rear axle and an upper divergiug section attached to the longitudinal springs and to straps which are secured to the body, substantiallyv as shown, and for the purpose set forth.

6. Ina vehicle having running-gearof ordinary construction, the upwardly and inwardly projecting bars C, att-ached to the rear axle so that their ends will be on aline with the bolster which is secured to the forward axle, side s] nings attached to the bolster and said bent bars, and means i'or Connecting the same to the wagon-body, substantially as shown, and for the purpose set l'orth.

In testimony whereo1.'I atlix my signature in presence ol' two witnesses.
